I am finding that many of the crypto's on the market have no use case what so ever, its very frustrating as an investor to research hundreds of useless cryptos.  They are just simply a tool to gain wealth from investors. 
I did find one crypto with an amazing use case and that is Horizon State - HST - decision token. Its a voting platform on the block chain.  The votes lodged on the block chain are unhackable, extremely cost effecting and voting results are instant.  I just cannot understand why all governments of the world are not voting on the blockchain, it makes logical sense to save taxpayers money and create a secure voting platform.
